Practice all four AP Computer Science A free-response question types with rubric-based scoring. The FRQ section is 50% of your AP CSA score and always contains the same 4 question types.
The 4 AP CSA FRQ Types
- Methods and Control Structures: Write or complete Java methods using conditionals, loops, and arithmetic. No class definition needed — just method bodies.
- Class: Design a complete Java class from a specification. Must write instance variables, constructor(s), and multiple methods. Tests encapsulation and object design.
- Array/ArrayList: Traverse and manipulate a 1D array or ArrayList. Typically involves searching, filtering, or rearranging elements based on a condition.
- 2D Array: Work with a 2D rectangular array. Almost always requires nested loops. Tests row/column traversal and element operations.
AP CSA FRQ Scoring Tips
Partial credit is available on every question — you can earn points for correct method signatures, correct logic, and correct output format even if other parts are wrong. Comments do not earn credit, but they don't lose it either. If you can't complete a method, write method stubs that compile to avoid losing syntax points on other methods that call yours.

What AP Computer Science free response rewards
AP CSA free response is four code-writing questions — methods and control structures, classes, array/ArrayList, and 2D arrays. The rubric awards points for correct logic even with minor syntax slips, so attempting every part and following the given method signatures exactly matters more than perfect compilation. AP CSP's written responses center on explaining your Create performance-task program plus exam questions on algorithms and data.
The mistakes that cost the most points
- Not matching the required method signature or return type.
- Off-by-one and boundary errors on array traversal.
- Leaving parts blank — partial logic still earns rubric points.
- CSP: describing what the code does instead of how the algorithm works.
